Low-graded coals to upgrade
Abstract: Coal can be defined as a chemically and physically heterogenous, “combustible”, sedimentary rock consisting of both organic and inorganic materials. Organically, coal consists primarily of carbon, hydrogen, and oxygen, with lesser amounts of sulphur and nitrogen. Inorganically, coal consists of a range of ash-forming compounds distributed throughout coal. Major types of analysis are proximate analysis, ultimate analysis and calorific value analysis. Heat value or calorific value determines energy content of …
